Packet - A unit of data sent over a network.
Passphrase - Used much like a password, a passphrase simplifies the WEP encryption process
by automatically generating the WEP encryption keys for Linksys products.
Ping (Packet INternet Groper) - An Internet utility used to determine whether a particular IP
address is online.
POP3 (Post Office Protocol 3) - A standard protocol used to retrieve e-mail stored on a mail
server.
Port - 1. The connection point on a computer or networking device used for plugging in a cable or
an adapter. 2.
The virtual connection point through which a computer uses a specific application on a server.
Power over Ethernet (PoE) - A technology enabling an Ethernet network cable to deliver both
data and power.
PPPoE (Point to Point Protocol over Ethernet) - A type of broadband connection that provides
authentication (username and password) in addition to data transport.
PPTP (Point-to-Point Tunneling Protocol) - A VPN protocol that allows the Point to Point Protocol
(PPP) to be tunneled through an IP network. This protocol is also used as a type of broadband
connection in Europe.
Preamble - Part of the wireless signal that synchronizes network traffic.
RADIUS (Remote Authentication Dial-In User Service) - A protocol that uses an authentication
server to control network access.
RJ-45 (Registered Jack-45) - An Ethernet connector that holds up to eight wires.
Roaming - The ability to take a wireless device from one access point's range to another without
losing the connection.
Router - A networking device that connects multiple networks together, such as a local network
and the Internet.
RTS (Request To Send) - A packet sent when a computer has data to transmit. The computer will
wait for a CTS (Clear To Send) message before sending data.
Server - Any computer whose function in a network is to provide user access to files, printing,
communications, and other services.
SMTP (Simple Mail Transfer Protocol) - The standard e-mail protocol on the Internet.
SNMP (Simple Network Management Protocol) - A widely used network monitoring and control
protocol.
Software - Instructions for the computer. A series of instructions that performs a particular task is
called a "program".
Spread Spectrum - Wideband radio frequency technique used for more reliable and secure data
transmission.
SSID (Service Set IDentifier) - Your wireless network's name.
Static IP Address - A fixed address assigned to a computer or device that is connected to a
network.
Static Routing - Forwarding data in a network via a fixed path.
Subnet Mask - An address code that determines the size of the network.
Switch - 1. Device that is the central point of connection for computers and other devices in a
network, so data can be shared at full transmission speeds. 2. A device for making, breaking, or
changing the connections in an electrical circuit.
TCP/IP (Transmission Control Protocol/Internet Protocol) - A network protocol for transmitting data
that requires acknowledgement from the recipient of data sent.
Telnet - A user command and TCP/IP protocol used for accessing remote PCs.
TFTP (Trivial File Transfer Protocol) - A version of the TCP/IP FTP protocol that uses UDP and
has no directory or password capability.
Throughput - The amount of data moved successfully from one node to another in a given time
period.
TKIP (Temporal Key Integrity Protocol) - a wireless encryption protocol that provides dynamic
encryption keys for each packet transmitted.
Topology - The physical layout of a network.
TX Rate - Transmission Rate.
UDP (User Datagram Protocol) - A network protocol for transmitting data that does not require
